13 Claims.

This invention relates to'safety razors of the magazine type organized to receive as desired a sharp and unused blade from a pack supplied in a magazine or clip. In one aspect the invention 5 comprises a novel combination of safety razor and magazine in which the razor is organized to receive from the magazine a blade directly in shaving position whereupon the magazine may be removed, relinquishing the blade already positioned in the razor and carrying away those blades remaining in the pack. In another aspect the invention consists in a novel magazine or clip for safety razor blades adapted for use in the combination described and for dispensing blades to the consumer. The magazine is not herein claimed since it constitutes the subject matter of my copending application, Serial Number 196,259, filed March 16, 1938. I

The extreme thinness of safety razor blades 1 and the fragile character 01 their shaving edges makes these blades diflicult to handle and locate ready for shaving in the razor without danger of cutting the user or of impairing the keen edge of the blade by contact with the razor or the blade packing. As herein shown the magazine of my invention is shaped to contain a plurality of blades in a stack or pack, maintaining their cutting edges out of contact with all parts of the magazine and exposing only the bodyof the lowermost blade in the pack so that it may be directly presented in shaving position in the razor. The razor, on its part, is designed to guide the magazine accurately into the proper blade delivlering position, to locate it properly when o'nce positioned and to guide the magazine again while it is moved to release the blade so positioned.

To the ends above set forth an important feature'of the, invention consists in a magazine or clip of sheet metal, containing no moving parts and being capable of production at low cost so that it may serve the purpose of a blade package in distribution; Its construction is such,,moreover, as to guard and protect the keen shaving edge 01' each blade contained therein up to the moment when it is deposited in shaving position in the razor.

These and other features of the invention will be best understoodand appreciated from the following description thereof, selected for purposes of illustration and shown inthe accompanying drawings, in .which gig. I is a view of the safety razor in front elewe on; a

Fig. 13 is an end showing the location the razor.

The razor shown in Figs. 1-3 is designed to take a narrow, straight, single-edged blade 50 of the type shown in Fig. 4 and is provided with a bladeseat for accurately positioning the blade and a 1 cap cooperating therewith to hold the blade in place and for protecting the user. In these figofa' blade for shaving in ures the razor is shown on about a one and onehalf scale. It comprises a stationary cap member and a movable blade carrier. The cap member is stationary and is preferably made of sheet metal and has a vertical stem portion II, a forwardly and -upwardly inclined body portion l2 and a downwardly inclined flange l3 which overhangs the blade when the razor is organized for shaving with a blade therein.

The blade carrier is also formed of sheet metal and has a body portion l4 hinged for swinging movement upon a horizontal pivot l5 mounted at the upper end of the stem portionil. It has also a forward'and downwardly inclined blade seat l6 and a rearwardly and downwardly inclined guard flange i1 and is perforated for the The blade seat i6 is provided 5 with a longitudinal rib it from which projects a pair of spaced blade-engaging pins i9. As shown in Fig. 4 the blade is provided with spaced apertures 5l to-fit upon these pins which thus deter mine accurately the shaving position of the blade. A sheet metal spring 20 is secured to the stem ii and tends always to swing the blade carrier upwardly toward the body portion l2 of the cap member. The cap member is provided with a slot and through this extends a projecting headed view on a still larger scale 20 swung downwardly and forwardly into blade receiving position as shown in Fig. 2. The blade seat it is provided near its outer or lower corners with'a pair of projecting guard lugs 22 which mask the corners of the blade and so protect the user from being cut or scratched by them. The blade seat is also provided at one end with a pair of spring fingers 23, shown on a large scale in Fig. 13, and adapted toengage one end of a blade placed upon the blade seat and .to hold it frictionally in place thereon pressingyieldingly an longitudinally against the pins I3.

It will be understood that the blade carrier may be swung into its blade receiving position as shown in Fig. 2 by pressure upon the stud 2| and that a blade 50 may then be positioned upon the pins l9 by placing it on the blade seat and forcing it slightly toward the left as seen in Fig. l, placing the spring flngers 23 under tension and bringing the blade apertures 5| into registration with the pins l9. When this has been done and pressure upon the stud 2| released, the blade car-- rier immediately swings upwardly carrying the rear portion of the blade 50 beneath the flange l3 of thefcap member. This flange |3 and the guard flange H of the blade carrier act as cooperating guard surfaces to determine a safe edge exposure for the blade.

A preferred embodiment of the blade magazine or clip of my invention will now be described and then it will be explained how this may be utilized in connection with the razor already described. The magazine may be formed substantially or entirely of sheet metal. It is generally rectangular in form and square in cross-section, having a front wall 30 which terminates in an inturned flange 3|. The magazine has also a top wall 32 and a rear wall 33 which is extended downwardly below the edge of the front wall 30 so that it provides a guide flange projecting below the body of the magazine.

The rear wall is also provided with an inturned flange 33 corresponding to the flange 3| of the front wall and spaced therefrom so as to expose the body portion of the lowermost blade in the pack by a distance just equal to the width of the rib "on the blade seat of the razor.

- In effect the bottom of the magazine is slotted or apertured to the width of the space between the inner edges of the flanges'jl and 33. The rear wall 33 is also provided with an external rib 35 which is located slightly above the level of the flange 33. It is herein shown as a solid rib but may be formed as corrugation in the metal of the magazine. From the description thus far it will be seen that the magazine is adapted to contain a pack or stack of blades 50 arranged longitudinally one above another, the lowermost blade being supported by and exposed between the inturned flanges 3| and 33.

The inturned flanges 3|- and 33.0f the maga-s zine are cutoff somewhat within the left end .of the magazine as shown in Fig. 8 and are provided at their right end with downturned ears or hooks 3| which act as stops to limit the movement of the magazine toward the left upon the blade seat of the razor. The flanges are out off at their left ends to facilitate disengagement of the blade when the magazine is'retracted, as. will be presently explained, and to eliminate the danger of prying up the blade uponthe blade seat by accidental tilting movement of the magazine at the end of its withdrawing movement. At its right end the magazine is provided with a long end wall i i end with a shorter end length as just to clear the lowermost blade in the gages the magazine 31 which extends from the top 32 of the magazine downwardly beyond the end of the lowermost blade supported upon the flanges 3|, 33. The magazine is correspondingly provided at its left wall 33 which is of such pack and so permit that blade to be moved endwise beneath the wall, or to permit the blade to remain at rest while the magazine is moved endwise to relinquishthe blade. The magazine is also provided internally upon its front wall 33 with a pair of-spaced vertical blade-guiding ribs 38 which are arranged to engage the sharp edges of the blades in the stack only at their extreme outer corners in such manner that the cutting edge as a whole is prevented from coming in dulling contact with the magazine. The guide ribs 39 also terminate in position to clear the lowermost blade in the pack and so leave its cutting edge entirely free for the retracting movement of the magazine. The magazine is also provided with a curved leaf spring 33 located below its top wall and tending at all times yieldingly to press the blade pack downwardly and into contact with the flanges 3| and 33.

In using the magazine above discussed to supply blades to the razor of Figs. l3, the stud 2| of the razor is depressed to swing the blade carrier forwardly into blade-receiving position and the magazine is placed upon the blade seat with the wide flange formed by its rear wall 33 in contact with the rear face of the body portion l3 of the blade carrier, as best shown in Fig. 11. The magazine may be placed in this position and then guided in this movement by its downwardly extending flange. The stud 2| is now released and the blade carrier will be moved rearwardly with the magazine until the rear wall of the magazine encounters the forward edge of the flange i3 of the cap as shown in Fig. 11. The flange |3 enjust above its external rib 35, or interlocks with the rib and, therefore, tends not only to push the magazine forwardly upon the blade seat but to hold it down against removal. The movement of the magazine toward the left is continued until arrested by engagement of the stops 3| against the right hand edge of the blade seat. This movement of the magazine is gauged by the stops so that the lowermost blade 33 in the magazine is forced at its left- -hand end against the spring flngers 23 displacing them outwardly and itself coming into registration with the pins is. It will be noted that in this movement the spaced flanges 3| and 33 of the magazine engage between them the rib ll of the blade seat and are guided thereby, all as shown in Fig. 11.

When the lowermost blade has been positioned as above explained it remains only for the userto move the magazine bodily toward the right, as suggested inligs. 9 and 10, leaving the blade positioned upon the blade seat. In this movement the magazine is again guided by the contact of its downwardly extending flange with the body portion ll of the blade carrier and by the engagement of its flanges 3| and 33 with the rib l3. During this movement it is also held against displacement by the engagement of the flange |.3 of the cap with its external rib 35. Inside the magazine the constant pressure of the spring 33 upon the stack of blades assists in forcing the lowermost blade upon the pins l3 and in avoiding the accidental removal of the positioned blade from the blade 7 in the magazine seat during withdrawal of the magazine; Movement of the magazine toward the right is continned until the magazine is entirely withdrawn from the blade, the latter passing under the wall 36 and being left in shaving position without any in the pack when the magazine has been drawn clear of the cap member of the razor. When the magazine has been, moved to the right sufliciently to clear the'razor the spring 20 is effective to J restore the blade carrier and the blade 50 to shaving position beneath the flange B of the cap as shown in Fig. 13 and the razor is ready for shaving.

After shaving; the used blade may be removed from its seat either by prying up one end of the blade sufficiently to disengage one of the pins I9, or by smartly shakingthe opened razor so that the frictional engagement of the fingers 23 is overcome to the .extent of releasing the blade.
